URL Structure for Q2A website hosted in wordpress website directory

Sat, 04 Feb 2023 09:32:31 +0000

Hello,

I installed q2a on my wordpress website subdirectory (htdocs) example.com/q/ and working url structure is /?qa=123/why-do-birds-sing

I want to change url structure to example.com/q/123/why-do-birds-sing [q2a general setting > option 1] but when i select first option and open example.com/q/123/why-do-birds-sing url then it's showing 404 error of wordpress theme 404 page.

My wordpress website is installed on UBUNTU server with Nginx.

I didn't want to have a common database for wordpress site and q2a site so that is why i want to host q2a on separate database with wordpress website.

When i try to move q2a outsite htdocs folder usinf FTP then it's showing wordpress theme 404 page.

Note - There are page rules on my main wordpress website which redirect all urls to home page or on specific page if url have ? symbol.

What should i do to have plain url structure (Defauld Q2A first option in general setting).

.htaccess file is -

Options -Indexes
DirectoryIndex index.php
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} libwww-perl.*
RewriteRule .* – [F,L]
#RewriteBase /
RewriteCond %{REQUEST_URI} ^(.*)//(.*)$
RewriteRule . %1/%2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ index.php?qa-rewrite=$0&%{QUERY_STRING} [L]
</IfModule>

Q2A running in Docker hosted on AWS. How can I send mail to users?

Fri, 24 Jun 2022 19:08:16 +0000

I've got Q2A running in a Docker container on an AWS EC2 instance. What additional work needs to be done past a base install in order to send mail to users? For example, if I want users to confirm their email before being able to make posts. I do not need the site to receive any emails, just the ability to send (please correct me if this is not the case)

I know there is an Emails section of the Admin page, but I feel like I am missing some SMTP server installation or something, as none of my changes on that page seem to make a difference.

When I send a test message to myself from Admin/Mailing, the page simply states "A server error occurred - please try again."

Do I need to install an SMTP server on my AWS instance to handle outgoing mail? Am I missing some part of the installation?

UPDATE: The container in which Q2A was hosted did not have the `sendmail` program installed. After installing, I no longer get the aforementioned "A server error has occurred," however now the page just hangs when I click "Send test to me." After a while, it claims to have sent a test message to my email, but I receive no email in any folders.

Still not sure what to do here...

"Table 'dbname.qa_options' doesn't exist"

Fri, 13 May 2022 05:18:48 +0000

I've installed question2answer on a server from these instructions on an Ubuntu 22.04 server in AWS with Apache/2.4.52 and MariaDB Ver 15.1 Distrib 10.6.7-MariaDB. There are no plugins being used.

Whenever I get to step 9, I get a 500 error, and when I look at the logs, I see that I'm getting this error--

Uncaught mysqli_sql_exception: Table 'dbname.qa_options' doesn't exist in /var/www/html/qa-include/qa-db.php:227

I've double- and triple-checked the database credentials. And it also looks like qa_db_create_table_sql is not being called at all.

I see there are similar questions asked here through the years, but I'm finding no answers relevant to my setup.

I'm going to try to continue debugging this on my end to try to find out why this function isn't being called, but if anyone knows how to resolve this, please let me know.

Update: As a workaround, I put this at the beginning of qa_index_set_request() in qa-include/qa-index.php.

     // MANUAL CORRECTION.
     // install if request_uri is "install-0462"

     if ($_SERVER['REQUEST_URI'] == '/install-0462') {
             $msg = 'Starting manual fix for broken installation process.';
             error_log($msg);

             require QA_INCLUDE_DIR . '/db/install.php';

             qa_db_install_tables();
             qa_db_upgrade_tables();

             $msg = "Completed installing.";
             error_log($msg);

             exit();
     }

     // END MANUAL CORRECTION.

Then I just went to /install-0462 and it installed correctly.

That doesn't fix the problem, I guess, but it's working correctly otherwise, so far. I also had to manually change the user permissions to get an admin user.

How do I install this app on my server?

Sun, 05 Apr 2020 18:31:33 +0000

Hi,

I want to start using this app as my primary Q&A web app but I can't seem to see any installation procedure anywhere on the net even including its github page. So anyone want to help out with installation docs?

mysqli::error is empty

Thu, 14 Nov 2019 19:17:30 +0000

I am trying to set up Q2A inside a docker container (running Ubuntu 18.04). I am able to get it to connect to my (empty) DB, but am then running into problems with the installation. First off, if I just visit the base URL, I get this:

Your Question2Answer database has been checked with no problems.

Go to admin center

Clicking the link effectively does nothing as I get served up the same page again. Time to roll up the sleeves and go code diving.

After exploring for a while, I tried manually accessing the URL: index.php?qa=install

This then gave me:

Database set_charset error

Seemingly not very helpful on the surface, but what it has so far boiled down to is that the call to mysqli::set_charset() inside of qa_db_connect() is returning false, and yet mysqli::$errno and mysqli::$error are both empty immediately afterwards. Here is the code in question (from line 94 in qa-include/qa-db.php):

if (!$db->set_charset('utf8'))

qa_db_fail_error('set_charset', $db->errno, $db->error);

Googling this issue so far is turning up nothing helpful unfortunately. If I try setting up Q2A on my development server (in a Joomla sub-directory, incidentally) I don't run into these problems and get t the page prompting me to set up the database.

As far as I can tell, my docker container is configured correctly. I am using Apache, PHP-FPM (7.3) and have installed the following php extensions:

ii php-common 2:70+ubuntu18.04.1+deb.sury.org+6 all Common files for PHP packages

ii php7.3 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 all server-side, HTML-embedded scripting language (metapackage)

ii php7.3-cli 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 command-line interpreter for the PHP scripting language

ii php7.3-common 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 documentation, examples and common module for PHP

ii php7.3-curl 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 CURL module for PHP

ii php7.3-fpm 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 server-side, HTML-embedded scripting language (FPM-CGI binary)

ii php7.3-gd 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 GD module for PHP

ii php7.3-intl 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 Internationalisation module for PHP

ii php7.3-json 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 JSON module for PHP

ii php7.3-mbstring 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 MBSTRING module for PHP

ii php7.3-mysql 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 MySQL module for PHP

ii php7.3-opcache 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 Zend OpCache module for PHP

ii php7.3-readline 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 readline module for PHP

ii php7.3-xml 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 DOM, SimpleXML, WDDX, XML, and XSL module for PHP

ii php7.3-zip 7.3.11-1+ubuntu18.04.1+deb.sury.org+1 amd64 Zip module for PHP

Lastly, out of curiosity, I tried ignoring the false return from set_charset and allowing the code to proceed. With that change, I then get a similar error on the first SQL query executed:

Database query error

SELECT title, content FROM qa_options

Again, the query called returned false and yet the error details are empty. Any clues greatly appreciated!

Error in Q2A ajax chat installing error

Sat, 01 Dec 2018 09:38:18 +0000

I am trying to install "qa ajax chat widget". There are steps to be performed:

Set the database access values in chat/lib/config.php.example and then rename it to config.php.
// I have performed above step successfully.
Then load "qa-plugin/adchat/chat/install.php" from the browser after prepending with the Q2A url.
// Does above instruction mean " gateoverflow.net/qa-plugin/adchat/chat/install.php " ? If yes, then page is not found error on Q2A site. It did not successful, Why?
Delete install.php - Running this again causes the chat database to be deleted.
// I deleted this file from hosting site.
Now, Go to "/admin/layout" and you can create a sidebar widget for chat.
// I created sidebar for qachat
Also, in "/admin/pages" new pages can be created for full page chat as well as chat logs (chat logs can be searched).
// I did not perform this step as there is error on chatting

There is an error :

Query: SELECT userID, userName, userRole, channel, UNIX_TIMESTAMP(dateTime) AS timeStamp, ip FROM `gateover_dd`.ajax_chat_online ORDER BY LOWER(userName); Error-Report: Table 'gateover_dd.ajax_chat_online' doesn't exist Error-Code: 1146

Please note that I have set these database values:

// AJAX Chat config parameters:
$config = array();

// Database connection values:
$config['dbConnection'] = array();
// Database hostname:
$config['dbConnection']['host'] = 'localhost';
// Database username:
$config['dbConnection']['user'] = 'qachatuser'; // I renamed as my username
// Database password:
$config['dbConnection']['pass'] = 'password'; // I renamed as my username password
// Database name:
$config['dbConnection']['name'] = 'qachat'; I renamed as my database name
// Database type:
$config['dbConnection']['type'] = null;
// Database link:
$config['dbConnection']['link'] = null; // what should be here?

After these entries I have renamed config.php.example to config.php .
AJAX chat is not working I did you run the "install.php" but result was not successful.

Could you please explain why are these showing error?
Thanks in advance.

Why are there two different zip files for download/install

Fri, 16 Mar 2018 15:11:47 +0000

The installation instructions say to "Download the latest version of Question2Answer " but under the latest release 'Assets' on the linked page there are two zip files "question2answer-1.8.0.zip" which downloads a file of that name and "Source code (zip)" which downloads a file called v1.8.0.zip.

Is the content of these zip files the same? In which case why have two? If not, how should we choose between them and shouldn't there be some explanation of that?

Problem installing Q2A V 1.8.0

Source code dowload link in the latest version is incorrect?

Sun, 29 Oct 2017 03:05:46 +0000

Dear Sir or Madam:

On: https://github.com/q2a/question2answer/releases

It looks like the download of the Source code is giving the wrong (same link) as primary download. These two are accessing the same zip file, but when one hovers over, they point to two different zips. Can you please fix or comment?
